Describe the value in the 're' column of vmstat(8) in terms of freebsd's vm

implementation. The old description was left over from the 4.4 BSD Lite import in 1994, and was a bit misleading (not all arches use simulated reference bits, some implement reference tracking in hardware).

Remove commented-out lines describing the old never-implemented -t option.

In 2018, r338094 removed the commented-out code for supporting the -t command line option which had been present since the BSD 4.4 Lite import, but was never implemented for freebsd. This does the same for the man page.

Update various statements in vmstat(8) to match reality.

2018-01-18T19:43:02Z

- The process stats are actually thread counts rather than process counts. - Simplify various descriptions to remove mention of stats that are updated every 5 seconds (all VM related stats are now "instant", only the load average is updated every 5 seconds). - Don't make any mention of special treatment for processes that have been active in the last 20 seconds. We don't track that stat. - Rework the description of active virtual memory. Call it mapped virtual memory and explicitly point out it is not the same as the active page queue (which corresponds to "Active" in top(1)), and also hint at the possible bogusness of the value (e.g. if a process maps a single page out of a multiple GB file, the entire file's size is considered mapped). - Simplify a few descriptions that implied their output was a value per interval. All of the "rate" values are per-second rates scaled across the interval. - Update a few comments for 'struct vmtotal' along similar lines.

Renumber copyright clause 4

Renumber cluase 4 to 3, per what everybody else did when BSD granted them permission to remove clause 3. My insistance on keeping the same numbering for legal reasons is too pedantic, so give up on that point. Submitted by: Jan Schaumann Pull Request: https://github.com/freebsd/freebsd/pull/96

Update vmstat usage for last-argument count/wait parameters

2014-08-08T16:32:06Z

Correct the usage in both the manpage and in usage() to indicate that the wait interval and repetition count may be given either with the respective -w/-c arguments, or as the final positional arguments. [0] The corresponding code to implement the positional arguments has been conditional on the (always-enabled) BACKWARD_COMPATIBILITY macro since the original 4.4-lite import. It's no longer reasonable to remove the functionality, so remove the macro and conditional instead. Note that multiple disks may be given on the command line. While here, sort arguments and apply minor mdoc fixes. PR: 184755 [0] Approved by: hrs (mentor, src committer)
